MATTRESS.

Specification of Letters Patent No. 4,896, dated December 17'-, 1846.

To all 'whom z'f may concern.'

Be it lmown that I, WILLIAM H. RoBERT ,soN, of New London, in the county of New ter which distinguishes it from all other things before known and of the manner of making,vconstructing, and using the same, reference being had to the accompanying drawings, making part of this speciicatio-n, in which- Figure 1 is a perspective view of a complete mattress, Fig. 2 a vertical section to eX- hibit the manner in which the mattress is constructed, and Fig. 3 a perspective view `of the mattress with the ticking removed.

The same letters indicatelike parts in all the figures.

The use of cotton has repeatedly been essayed for making mattresses and failed to produce desirable results for the reason that the cotton employed was simply carded or opened with the ingers and put within a cover in the same manner as horse hair, moss, or other materials, and in that condition soon became matted together and in a great measure lost its elasticity; but this ditliculty is avoided by my improvement which consists, first in making the mattress of several layers of well glazed cotton batting (or unglazed batting with glazed paper or cloth interposed between each layer of cotton batting) confined in a proper manner within a ticking or other covering; and secondly, in confining the layers of cotton batting while under pressure between two cloths, forming the top and bottom, the edges of which are connected together 'by cords that pass alternately from one to the other, and temporarily fastened until placed within a ticking sothat when this latter is nearly sewed up the cord can be liberated to permit the cotton to expand to the full capacity of the ticking which can then be entirely closed up, the cord or cords being left of sufficient length to admit of drawing together the inner top and bottom cloths when desired to remove the ticking when required to be cleaned or renewed. l

. l In the accompanying drawings (a, 05,)

represent two cloths composing the top and bottom between which are placed the required number of layers of well glazed cotton batting (5,) which are then pressed down and the edges of the two cloths' connected by running cords (c) that pass alternately through one and then the other. When these two covers arethus connected the pressure is removed, and-the whole put within a ticking (ci) made in the usual manner and when nearly sewed up the cords are liberated to permit the cotton to swell out to fillrup the ticking entirely; the cord or cords being made of sufiicient length for this purpose and also to admit of drawing them up whenever it becomes necessary to remove the ticking for washing, &c.

The process of making such mattresses or beds which I have essayed andr deem the best, is to place the lower cloth (a) onthe bed of a press. On this the required number of glazed cotton battings are placed, and covered with the upper cloth a1). The follower of the press is'then forced down unt-il the mass is reduced .sufliciently to admit of introducing it within the ticking (ci), and when this is done the edges of the two cloths (a, a,) are connected together by the cordsL cotton, thus secured, placed within the tick-y ing, which is secured in the usual manner, except that before the edges are entirely sewed up the temporary fastening of the cords (c) is liberated to permit the cotton to swell out suliiciently to lill the ticking which is then entirely closed up.

-It will be obvious from the foregoing that mattresses can be made according to the. first part of my invention with only one ticking, although I prefer to make them with the inner fastening above described to facilitate the introduction of the cotton battingy in the ticking, and to admit of taking Cif and put.- ting on the ticking. The cotton batting is to be coated or glazed with glazing matter made of animal glue or other glutinous substance or substances, and it is desirable that it should be so compounded as not to 'be affected by moisture at the temperature to which beds are exposed.

What I claim as my invention and desire to secure by Letters Patent isl. Making mattresses by confining Within a ticking or tiokings, (made of any material), layers of glazed cotton batting ,or unglazed batting With glazed paper or cloth interposed7 substantially as described, to

l0 means of a cord or cords, When this is combined With a ticking or outer covering, substantially as above described, whereby the cotton can be retained, byV the cords and cloths, in a state sufficiently compressed to admit of its being easily introduced in the 15 ticking or removed therefrom as described.
